COMBINATION-TOOL.

SPECIFICATION forming part of Letters Patent No. 776,987, dated December6, 1904.

Application filed October 26, 1903, Serial No. 178,654. (No model.)

To all whom, it may concern.-

Be it known that 1, ANDREW PETER BERG- GREEN, a citizen of the UnitedStates, and a residentof EllillOI'll, in the county of Shelby and Stateof Iowa, have invented new and useful Improvements inCombination-.lools, of which the following is a full, clear, and exactdescription.

This invention relates to certain novel and useful improvements incombination-tools, and has particular application to an implementdesigned to embody in its construction a carpenters pincers or pliers, anail-puller, and a plurality of wrenches.

A further object of my invention is to provide an implement which willbe extremely simple in its construction, the arms and jaws forming thebody portion thereof being connected in such a manner that they may beeasily separated and each one of the members may be used as a wrench.

Still another object of the invention is to form an improved nail-pullerat the ends of thejaws of the pincers,said nail-puller being soconstructed and arranged that nailsflush with thes urface of a boardorcountersunk therein, may be easily and readily removed without cutting,marring, or injuring the board.

With the above-recited objects and others of a similar nature in view myinvention consists in the construction, combination, and arrangement ofparts, as is described in this specification, delineated in theaccompanying drawings, and set forth in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of an implement constructed in accordancewith my invention and showing it in position for drawing a countersunknail from wood. Fig. 2 is a side elevation, partly in section, showingthe tool in the position of Fig. 1. Fig. 3 is a detail perspective viewof the pivotbolt detached from the members of the implement, and Fig. &is a perspective view looking at the jaws and the claws thereon.

Referring now to the accompanying drawings in detail, 5 and 6 designatethe arms or members forming my improved pincers or pliers, each memberhaving a relatively widened and flattened portion formed thereon, asshown at 7 and 8, the flattened portion 7 having a shoulder or extension9 projecting therefrom, upon which shoulder is adapted to seat the lowerextremity 10 of the flattened portion 8 of the arm 6. The flattenedportions 7 and 8 are provided with transverselyextending apertures 11and 12, said apertures being designed to register when the members areassembled and to permit the passage of the connecting pivot-bolt 13, thehead portion 14 of said bolt bearing against one of the Hattened sides,while in the opposite end of said bolt is formed a small bore 15,through which passes the securing-pin 16. The lower portions of themembers form the ordinary jaws 17 and 18; but formed on each jaw is arelatively small projecting claw 19, these claws being designed to bebrought into contact when the jaws are closed and are so shaped andcurved that they will readily engage with the head of a nail even thoughthe latter be countersunk, and said nail may be readily removed withoutbruising or injuring the surface of the wood, as is commonly the casewith the ordinary implements now in use. As will be noted, these claws19 are formed at the edges of the jaws and are relatively short whencompared with the length of the working edges of the jaws of the tool.

The member 5 has formed at its upper end a wrench-head, as shown at 20,while a second wrench-head 21 is formed at the end of the member 6, saidheads being of relatively different sizes.

By reference to Figs. 1 and 3 of the d rawings it will be seen that theclaws 19 lie very close to that side of the instrument having theprojecting head let of the pivot-bolt, and these claws 19 are muchnarrower than the jaws 17 18 of the implement, said claws being providedwith sharpened active edges. The pivot-bolt 13 is provided between itsshank and the head 14 with an angular or polygonal portion 22, the samebeing adapted to fit into a correspondingly-shaped opening which isprovided in the large portion 7 of the member 5. It will be understoodthat the pivot-bolt 13 is fitted to the openings 11 12 of the members 56 in a way to bring the angular or polygonal portion 22 of said boltinto the correspondingly-shaped opening in the member 5, whereby thehead 1 1 is brought quite close to one side of the implement, and theperforated end of the pivot-bolt is adapted to receive the key orfastener 16-. The provision of the angular or polygonal portion 22 onthe pivotal bolt serves to hold the head 14 at all times in positions toreceive the blow of a hammer or other instrument when the implement isemployed for the purpose of driving the claws 19 into the wood, so as tomake the claws embed themselves in the wood and engage with a nail belowthe head thereof, substantially as shown by Figs. 1 and 2. The head 1 1of the pivotal bolt is tapered from one side of the bolt to thestriking-face 14:, which is provided at the free end of said head.

In using my implement to draw nails from wood when the heads of thenails project slightly beyond the surface it is not necessary to employthe claws 19, becausethe biting edges of the jaws 17 18 can easilyengage with the nail below the head thereof; but when the nail-head iscountersunk in either hard or soft wood it becomes necessary to employthe claws 19. 1f the implement is used on soft wood, it is onlynecessary for the workman to press forcibly on the members 5 6, so as toembed the claws 19 into the wood on opposite sides of the nail, afterwhich the claws may be closed to grip the nail, and the implement can beoperated to withdraw the nail from the wood by the action of the claws,after which the implement may be shifted so as to bring the jaws 1718into engagement with the nail, and by turning the implement in anydirection these jaws will extract the nail, the curved faces of the jawsserving to bear and turn easily on the wood for the purpose ofextracting the nail without marring or bruising the surface of the wood.

In using the instrument to extract countersunk or flush nails from hardwood the operator should first adjust the jaws adjacent to thenail-head, and by striking the head 14: of the pivotal bolt a blow witha hammer the claws are forced into the wood and the implement ismanipulated in the described manner to extract the nail practicallywithout marring the surface of the wood.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A tool of the character described, comprisingmembers provided with jaws having extracting-claws located at one sidethereof and projecting in advance of the face of the jaws, said membersof the tool having regis tering transverse openings extending throughthem, the opening in one member being round and the opening in the othermember being round at its inner end and of enlarged polygonal shape atits outer end, a bolt extending through said openings to pivotallyconnect the members together, said bolt having one end round andreceived into the round portions of said transverse openings, and havingan enlarged polygonal portion adjacent to its round portion and fittingsaid polygonal portion of the opening in one of said members to hold thebolt against rotation thereon, the outer end of said bolt beyond thepolygonal portion being further enlarged and bent upwardly in directionof the handle end of the tool and having a flat inner side in engagementwith the side of the tool, and provided with a flat end facing upwardlyto forma striking-surface, said enlarged end of the bolt being on thesame side of the tool with the projecting claws and located verticallyabove the point at which said claws meet.

2. An instrument of the class described, comprising members providedwith jaws and with extracting-claws, and a bolt pivotally connectingsaid members, said bolt having a striking-head bent in direction of thehandle end of the members and fitted to one of the members to maintainthe striking-head normally in an active exposed position.

in testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
